There have been some ongoing discussions about whether or not to use
Narrow FM for uplink or downlink on AO-85. My observation is that
Narrow FM (Filter 2) for the downlink works best. For the uplink, I
leave Filter 1 enabled.
This is easy to do in your DOPPLER.SQF:
AO-85,145980,435175,FMN,FM,NOR,0,0,Transponder
The first FMN will set Filter 2 for your downlink
The second FM will set Filter 1 for your uplink.
I've also noticed Filter 3 makes LilacSat-2 sound best but I am
unaware of a command via SatPC32 to select that filter automatically.
